Title: Improvements in the manufacture of artificial filaments, yarns or threads by the dry or evaporative method
IPC: D01D5/20
Filed: 1929-11-18
Abstract: <PICT:0343973/IV/1> Artificial silk &c. yarns and threads, the filaments of which exhibit a periodic variation in cross section along their length, are obtained by periodically varying one or more of the factors which determine the evaporative conditions to which the filaments are subjected on extrusion.  Thus, mixtures may be made in the temperature at which the spinning solution is supplied to the spinning jet, the temperature of the evaporative atmosphere, the proportion of solvent vapour in that atmosphere, and the rate at which the temperative atmosphere is passed through the cell; or the concentration of the spinning solution or its viscosity may be varied.  By a suitable choice of conditions, filaments exhibiting at intervals along their length sections from flat to round, or having a smooth or irregular surface, or of solid or tubular and cellular structure may be obtained.  As shown, the spinning cell 9 is provided at the region of the spinning jet 5 with a perforated pipe 11 as described in Specification 325,233, [Class 2 (ii), Cellulose &c.], through which solvent-laden air from main supply pipes 18, 19 may be introduced as desired into the cell; it is preferred to have independent supplies of air and solvent-laden air as by means of the pipes 18, 19 respectively; the two branch supply pipes 12, 13 are provided with valves 14, 15 controlled by cam mechanism 22, 24, 25, the cams for actuating the pair of valves being on one shaft or on different shafts driven at the same speed and in the same phase or different phases, or being driven at different speeds.  The valve 28 controlling the flow of air from the cell may be actuated in a similar manner.  Similarly the supply of heating fluid either to the cell through the pipe 31 or through the pipe 8 to the tank 6 for heating the spinning solution may be automatically controlled; and it is convenient to employ in the tank 6 a fluid of low specific bent and high thermal conductivity so that variations in the supply of heat are rapidly transmitted to the spinning solution: alternatively the fluid in the tank 6 may be heated by an electric resistance automatically controlled.  Air is supplied to the cell through an inlet valve 33; and the rate of flow of the air so supplied and also its temperature may be controlled automatically.

Title: An apparatus for the sterilization or pasteurization of commodities in containers and a carrying element to be applied in such device

Abstract: 1,000,175. Endless chain conveyers. GEBR. STORK & CO.'S APPARATENFABRIEK N.V. Sept. 6, 1963 [Sept. 11, 1962], No. 35367/63. Heading B8A. [Also in Division A2] A conveyer in a food sterilization chamber (see Division A2) comprises T cross-section members 5 disposed between parallel chains 4. The base of the central leg 8 of each T member 5 is thickened so that each pair of adjacent members 5 provides a shaped recess for a respective can 6 (Fig. 4). Feed to and discharge from the conveyer are arranged adjacent return sprockets of the conveyer (Fig. 1, not shown), where adjacent thickened legs diverge apart. Each member 5 is terminated at each of its ends by a plate 9 which has semi-circular recesses in engagement under the flanged leads 12 of adjacent chain link pivot pins 13. Cut-away parts 10 of the plates 12 permit, but limit, flexure of the conveyer. A spacer 21 is secured to those plates 9 which are adjacent a chain link of each closely spaced pair of links, and fits in a locating recess 22 of the link. Each widely spaced pair of links is locked against movement relative to the pivot pins 13 by a pivot pin retaining plate 19. Feelers 29 moving in synchronism with the conveyer chain are carried by an arm 32 supported in neutral equilibrium by a pneumatic cylinder 33. When a can 6 is incorrectly positioned it engages a feeler 29 and thereby displaces the arm 32. This breaks an electrical contact 34 and stops the conveyer. In a modification (Fig. 5, not shown), the feeler may be mounted on a parallel linkage.

The coil may, as shown, be formed into an upright cylinder used for warming and evaporating liquefied gases. Atmospheric air flows downwardly through the coil which is mounted on legs 7. The chimney effect can be enhanced by placing a cylindrical body axially within the coil, by using a plurality of coaxial coils, or by using a waisted or convergent-divergent form of coil. The draught may be controlled by a baffle. The coil may be mounted around the lower part of a liquefied gas storage vessel, the fins 4 being cut away as necessary to provide access to valves &c. on the vessel.

Title: Process for preparing lactams from cyclic oximes
IPC: C07D201/04
Filed: 1977-09-02
Abstract: A process is described for preparing lactams from cyclic oximes by rearrangement of the oxime in a liquid medium, wherein a circulating reaction mixture is forced through a vortex chamber in which it passes through a fast cyclone flow and into which the oxime is fed in, or in the vicinity of, the axis of the cyclone flow via a metering tube. The metering tube is formed in such a way that the oxime can leave the latter at least partially in a direction which forms an angle with the axis of the cyclone flow.
